IL HB5328

Expands the 20 mph school zone speed limit to apply on "local, county, or State" roadways on public school property, clarifying jurisdiction beyond just public thoroughfares

Defines "school" to include public and private primary/secondary schools, religious schools, and nursery schools for purposes of the speed limit requirement

Sets school zone hours from 6:30 a.m. to 4:00 p.m. on school days when children are present and close enough to traffic to create a potential hazard

Expands park zone street definitions to include "State or local" streets adjacent to park zones that are designated by local ordinance, where 20 mph limits apply when children are within 50 feet of traffic

Maintains existing penalties: school zone violations carry $150 minimum fine (first offense) and $300 (subsequent); park zone violations carry $250 minimum fine (first) and $500 (subsequent), with enhanced misdemeanor charges for excessive speeding in school zones
